01. rear-27) 1 Claim.

This invention relates to improvements in climbing devices of the type used by linemen, lumbermen, and the like.

It has for its principal object the provision for a device of this character which will be comfortable to wear, quickly and conveniently detachable, either in part or in its entirety, from the leg of the wearer.

A further object is the provision of an adjust able climbing spike.

A further object is the provision of an adjustable shoe or boot clamping element which also may be detached from the device when not in use, if desired.

The foregoing and other objects will appear as my invention is more fully hereinafter described in the following specification illustrated in the accompanying drawing, and finally pointed out in the appended claim.

In the drawing;

Figure 1 is a front elevation of the device with parts in section for convenience of illustration.

Figure 2 is a side elevation of Figure 1.

Figure 3 is a front sectional view through the adjustable shoe clamping element.

Figure 4 is a detail view of a modified form of a shoe clamping element partly in section.

Referring now more particularly to the draw- Reference numeral I indicates a brace slotted, as at 2, at its upper end for removable engagement with a keeper 3, normally disposed at right angles to the slot 2, and s cured by any suitable means to a curved plate 4, The plate is lined with any suitable material 5; such as, rubber, leather, or the like, and is adapted to be secured to the leg of the wearer by straps 6 carried by belts I attached to the plate 4 by means of slots 8 formed therein.

At the lower end of the brace I, I provide a spike 9, slotted, as at III, to receive a bolt II for adjustable attachment to the brace. The spike is curved, as shown; and its rear surface is preferably knurled, or serrated, for engagement with a corresponding shaped and surfaced portion I2 of the brace. By this arrangement, the spike may be securely held in any adjusted position with respect to the brace.

The lowermost end of the brace terminates in a socket I3, adapted to receive a shaft I4 whose outer end is internally threaded, as at I5, to receive a binding screw I6 for securely mounting the shaft to the brace. Secured to the shaft I4, by welding or the like, and adapted to lie against, or adjacent to the inner end of the socket I3, is one element I1 of a shoe clamp. The companion element I8 of the shoe clamp is mounted to, or iormed integral with a sleeve I9, which is adjustably mounted on the inner end of the shaft !4 by means of an adjusting screw 20, adapted to be advanced or retarded on the internal threads 2! of the shaft I4. Thus the clamping elements may be conveniently adjusted into clamping engagement with the sole of a shoe, as shown in Figure 2.

With reference to the modified form of shoe clamping element shown in Figure 4, reference numeral 22 indicates the lower end of a brace, corresponding with that shown in Figure 1. The lower end of the brace is formed with a bushing 23, within which is securely mounted a shaft 24, internally threaded at its outer end to receive an adjusting screw 25. A plate 26, forming a foot support, is formed at its outer end with a depending ring 2'! for engagement with the outer end of the shaft 24. The opposite end of the plate 25 is formed with a depending and apertured bracket 28 for engagement with the bushing 23. One shoe clamping element 29 is formed integral with the plate 26 and extends upwardly therefrom. The companion shoe clamping element 30 is formed integral with a plate 3I, which is slotted, as at 3IA, to slidably embrace square projections 32 formed integral with the under side of the plate 26. An apertured projection 33 is formed integral with the under side of the clamping element 3| and rotatably embraces the adjusting screw 25, so that the clamping element 30 may be adjusted inwardly, or outwardly, with respect to the plate 26 and the companion clamping element 29.

While I have shown a particular form of embodiment of my invention, I am aware that many minor changes therein will readily suggest themselves to others skilled in the art without departing from the spirit and scope of the invention. Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:

A climbing device, comprising a keeper adapted to be removably secured to the leg of a wearer, a brace slotted at its upper end and adapted to be pivotally attached to said keeper to permit swinging movement between the brace and the keeper, a spike of arcuate formation, adjustably mounted to an arcuate portion of the brace near its lower end, a shoe clamping element adjustably and removably attached to the lowermost end of the brace, said clamping element compris-' ing a shaft having one element of the shoe clamping element secured thereto in a fixed position, and a companion clamping element adjustably and removably attached to the outer end of said shaft.
